Abstract: Technologies are generally described to communicatively couple an optical fiber to an optical element using a polymer layer. An optical fiber may be coupled to an optical element, such as an optical waveguide or another optical fiber, using a layer of rewritable photorefractive polymer positioned between the optical fiber and the optical element. Light from a light source may be applied to the optical fiber to initiate a transient photorefractive effect in the polymer layer facilitating corrections of misalignment. A path of high refractive index may be formed in the polymer layer, where the path of high refractive index communicatively couples the optical fiber to the optical element reducing alignment concerns and increasing alignment tolerances of optical elements. In some examples, the path of high refractive index may be re-established by rewriting the polymer layer through another application of light from the light source if the communicative coupling is disrupted.

Abstract translation: 技术通常被描述为使用聚合物层将光纤通信地耦合到光学元件。 可以使用位于光纤和光学元件之间的可重写光折射聚合物层将光纤耦合到光学元件，例如光波导或另一光纤。 来自光源的光可以施加到光纤上以在聚合物层中引发瞬时光折射效应，有助于校正不对准。 可以在聚合物层中形成高折射率的路径，其中高折射率的路径将光纤通信耦合到光学元件减少对准问题并增加光学元件的对准公差。 在一些实例中，如果通信耦合被破坏，则可以通过从光源的另一应用光改写聚合物层来重新建立高折射率的路径。
